so, it's probably and upgrade from what you have, but not the newest model, it says it will charge
battery, but does not say if it has smart charge capability.
if the one you have works, it might not be worth the effort.
I changed the guts of mine so that I had a new smart charging converter, but the old breaker box so I didn't have to fool with as much wiring. I installed a PD9145 converter in the space my old converters transformer section was mounted in
everybody has an opinion, you need to do what works for you
